Scope Gap is where coordination goes to die. 
 
The concrete isn't usually the problem. 
 
The problem is everything hidden inside it. 
 
In this Scope Gap minisode, Brian and Alex dig into one of the most coordination-heavy elements of any project: the slab on grade. From floor boxes and floor drains to control joints, conduit, reinforcement, and slab depressions, they explore how scope gaps get buried before the concrete truck even arrives—and why those gaps often become demolition plans later.

Show Notes 

The slab assumes: 

• Everyone coordinated the utilities. 

• The plumbing elevations are correct. 

• The conduit routing fits. 

• The control joints were coordinated. 

In practice, it becomes: 

• A coordination problem nobody owns. 

• A field decision made under schedule pressure. 

• A very expensive concrete saw. 

Takeaways: 

• Coordinate utilities before the pour. 

• Verify slab depressions, leave-outs, and floor boxes early. 

• Don't assume someone else owns slab coordination. 

• If the concrete truck is already on site, you're probably out of good options. 

"The slab problems rarely come from bad concrete. They come from decisions that never met each other before the pour."
